nRF Connect Toolchain fails

I followed your step by step guide available on your site for installing the SDK and Toolchain. My system are Fedora 36 with VS Code IDE, but the system detects the errors that I report attached in this screenshot:

and in the VS Code IDE output window appear those errors:

********** VS Code Output window content ***************

  • As I said in my previous reply, your error seems to be caused by your Python environment, and is probably caused by something you set up before you started installing NCS.

    See for example this thread for a similar issue: https://stackoverflow.com/questions/38132755/importerror-no-module-named-encodings

    If you were working in a virtual environment earlier, this seems likely to be the root of your issue.
